BMW 3: Climate Control

As in previous BMW hybrid vehicles, an electrically powered air conditioning compressor is used in the G20 PHEV. Because the A/C compressor has an electric motor, it is possible to operate the air conditioning independently of the combustion engine. Thus the customer can enjoy the cooling effect of the air conditioning even while driving in pure electric mode and while stopped.

The high-voltage battery unit is cooled by the vehicle's refrigerant's circuit.

The stationary climate control is also available in the G20 PHEV.
